Disclosure of Invention
The object of the present invention is to provide a device and a method for charging an electrical energy store of a motor vehicle, which enable the energy store to be charged particularly efficiently over time, wherein the motor vehicle does not need to have a self-control capability.
According to the invention, this object is achieved by a device having the features of claim 1 and by a method having the features of claim 10. Advantageous embodiments of the invention are the ones of the dependent claims.
The first aspect of the invention relates to a device for charging an electrical energy store, in particular a battery, of a motor vehicle, which device is also referred to as a device or is designed as a device. The device has a plurality of charging stations, by means of which the respective energy store can be supplied with electrical energy and thereby charged. The charging station is preferably individual devices which are arranged separately, next to one another and, if appropriate, spaced apart from one another, the individual devices forming the apparatus or being part of the apparatus in particular as a whole.
In order to be able to charge the energy store in a particularly efficient manner over time, the invention provides that the device has a conveyor system, also referred to as conveyor device or configured as conveyor device, by means of which a motor vehicle, which is preferably configured as a motor vehicle and is preferably configured as a passenger car, can be automatically transported from an extraction region of the device, which is spaced apart from the charging stations, to the respective charging station, from at least one first of the charging stations to at least one second of the charging stations, and from the respective charging station to a waiting region of the device, which is spaced apart from the charging stations and from the extraction region, that is to say can be transported. The extraction area is also referred to as a transfer area, for example, into which the respective motor vehicle can be driven by the respective driver of the respective motor vehicle. By means of the transport system, it is possible, for example, to automatically transport the respective motor vehicle from the extraction area to one of the charging stations which is or has been idle and which has been determined to be particularly advantageous for charging the energy store of the motor vehicle. Furthermore, the transport system may automatically transport the respective motor vehicle from the first charging station to the second charging station. Thus, for example, the respective energy store can be charged first and in particular during a first time period by means of a first charging station and then in particular during a second time period following the first time period by means of a second charging station. In this context, for example, the first charging station is better suited for charging the energy store than the second charging station during the first time period, wherein, for example, during the second time period, the second charging station is better suited for charging the energy store than the first charging station, or the potential of the first charging station, for example, the maximum charging power, can no longer be fully utilized during the second time period in order to charge the energy store also during the second time period. The energy store can thus be charged during the second time period by means of the second charging station, so that, for example, the first charging station can be used during the second time period in order to charge another one of the energy stores particularly quickly. The transport system can furthermore, for example, transport the respective motor vehicle from the respective charging station into the waiting area if the energy store of the respective motor vehicle is completely or at least sufficiently charged such that the current charge state of the energy store, which is caused by the charging, exceeds a predetermined charge level or a predefinable charge level, for example. This is advantageous in particular if the driver of the respective motor vehicle does not drive the respective motor vehicle away from the respective charging station after the energy store has been fully charged. As a result, it is possible to avoid that the respective charging station is blocked by the vehicle having the fully or at least sufficiently charged energy store, since the motor vehicle can be transported away from the respective charging station and transported into the waiting area. In this way, the respective charging station can be freed, i.e. can be provided for a further motor vehicle or a further energy store in order to charge the latter. The motor vehicle with the fully or sufficiently charged energy store can then be extracted by the driver in the waiting area and removed from the waiting area. The invention thus makes it possible to achieve a particularly advantageous vehicle logistics on or in the installation, so that the charging station of the installation can be used particularly advantageously in order to be able to charge a plurality of motor vehicle energy stores particularly rapidly, in particular also during so-called peak traffic times, in which particularly high traffic operators wish to charge their energy stores.
The invention is based on the following recognition and consideration: in conventional devices for charging energy stores of motor vehicles, a long waiting time can be observed during peak traffic times, for example during holidays, because the device with a plurality of charging stations for charging energy stores of motor vehicles and thus the charging infrastructure is conventionally not designed such that, for example, during peak traffic times, which can be determined empirically and/or by simulation, during which a plurality of drivers of motor vehicles equipped with electric energy stores wish to charge the electric energy stores, all energy stores can also be charged simultaneously or at least such that excessive waiting times do not occur, that is to say the drivers do not have to wait for a long time or at all in order to obtain an idle charging station and charge the energy stores by means of the charging station. This design of the charging infrastructure is too costly and proves economically unreasonable. In conventional installations, it is therefore necessary for each driver, together with his motor vehicle, to be queued in a train and to wait for such a long time until he leaves a charging station at which he can charge his energy store. The reason for this is, in particular, that there are mainly motor vehicles which do not have an automated driving function by means of which the motor vehicle can automatically, i.e. without driving by the driver, travel to an idle or idle charging station. The motor vehicle must therefore be driven by a person, and therefore by his driver, to the respective charging station. Thus, the driver must be present in the respective motor vehicle in order to drive the motor vehicle to the respective charging station. Since the driver must be present in the motor vehicle, a long time is created, which the driver must spend in the motor vehicle, but which can be used significantly more meaningfully outside the motor vehicle than when waiting charging stations become idle in a train. Furthermore, the time requirements for charging, also known as charging processes or occurring during charging processes, are often undesirable or unplanned. In general, the time required for the charging process cannot be calculated either immediately on the device or by the device nor by the digital system for route and/or charging planning. Another disadvantage or problem of the prior art may also be that the costly fast charging infrastructure, i.e. the fast charging station that can charge the energy store with very high charging power, is conventionally not used or becomes inefficient. If the driver does not drive his motor vehicle away immediately after the end of the charging process, since the driver has already started an activity which has not ended after the end of the charging process, for example, during the charging process, the motor vehicle with the fully or sufficiently charged energy store blocks the charging station, which is disadvantageous, in particular, if the charging station is configured as a rapid charging station. During a blockage, valuable time is lost in which the accumulator cannot be charged.
The invention is based on the further insight that the highest possible charging power with which the energy store can be charged by means of the charging station decreases with increasing state of charge, i.e. with increasing amount of electrical energy stored in the energy store. If, for example, a charging station, which is in particular configured as a rapid charging station, has a maximum charging power of, for example, 350 kw, the respective energy store can only be charged with this maximum charging power by means of the charging station until the state of charge of the energy store falls below a limit. Above this limit, the charging station can no longer charge the energy store with its maximum charging power, but only up to a charging power that is smaller than the maximum charging power. Thus, the quick charging station will not be able to be effectively and efficiently used.
The aforementioned disadvantages and problems can now be solved by the invention, in particular by the fact that the motor vehicle can be moved automatically and in a desired manner by means of the conveying system, in particular from the pick-up area to the respective charging station, from the charging station to the charging station and from the respective charging station to the waiting area. As a result, the charging station can be used effectively and efficiently, in particular with respect to its maximum charging power, so that a particularly large number of energy accumulators can also be charged in a short time, in particular completely or at least sufficiently, by means of the device according to the invention.
In particular, the transport system is configured such that it allows a respective driver of a respective motor vehicle, also referred to simply as a vehicle, to leave the motor vehicle, so that the driver can meaningfully spend his time outside the respective motor vehicle. The vehicle can thus be moved as desired by means of the conveyor system, while the driver is located outside the vehicle. The automatic transport of the respective motor vehicle is thus understood to mean that the transport system can transport the respective motor vehicle without the driver acting and without the driver staying in the motor vehicle. The transport system makes it possible in particular to transport the motor vehicle at least almost without delay to the respective point of the device, also referred to as the system, where the standstill of the motor vehicle is advantageous in order to optimize the overall process for charging the energy store, i.e. to implement the overall process for charging the energy store in a particularly advantageous manner over time, and thus to move the motor vehicle. In particular, by means of the invention, excessively long blocking of the charging station due to a motor vehicle having a fully or completely charged energy store can be avoided.
In a particularly advantageous embodiment of the invention, the transport system has at least one transport platform, which can also be referred to or constructed as a transport pallet or pallet, which can be moved at least translationally and preferably also rotationally, from the pick-up area to the respective charging station, from the first charging station to the second charging station and from the respective charging station to the waiting area. The respective motor vehicle can be parked on the transport platform and thereby transported by means of the transport platform at least translationally and preferably also rotationally from the pick-up area to the respective charging station, from the first charging station to the second charging station and from the respective charging station into the waiting area during the time the respective motor vehicle is on the transport platform. In other words, the respective driver of the respective motor vehicle can park his motor vehicle on the transport platform, in particular first in the pick-up area, and thus on the transport platform and subsequently leave his motor vehicle, for example. When the driver, also referred to as a user, is located outside his motor vehicle, the transport platform can automatically transport the motor vehicle parked on the transport platform from the pick-up area to the respective charging station. For example, one of the charging stations of the device is selected by means of the device, in particular by means of the electronic computing device of the device, and the motor vehicle is transported to the selected charging station by means of the platform. After the motor vehicle on the transport platform is transported to the selected charging station, the motor vehicle is charged by means of the selected charging station. The charging station selected is, for example, the first charging station mentioned previously. If the energy store of the motor vehicle is charged by means of the selected charging station in such a way that the energy store is fully charged or the current state of charge of the energy store, in particular caused by the charging, is greater than a predetermined or predefinable level, for example, the motor vehicle is moved by means of a platform from the selected charging station into a waiting area, from which the driver can pick up the motor vehicle and drive away. For example, when the motor vehicle is on the transport platform, the motor vehicle is charged by means of the selected charging station.
If, for example, the maximum possible charging power with which the motor vehicle can be maximally charged by means of the selected charging station is determined to be below, for example, the limit of the maximum charging power of the selected charging station, but the energy store has not yet been fully charged or the current state of charge has not yet reached or exceeded this level, the motor vehicle is transported from the selected charging station (first charging station) to the second charging station, for example, by means of a transport platform. At or with the aid of the second charging station, in particular during the time when the motor vehicle is on the conveyor table, in particular the energy store of the motor vehicle is charged in such a way or for such a long time until the energy store of the motor vehicle is completely charged or reaches or exceeds the previously mentioned level. During charging of the energy storage devices by means of the second charging station, the first charging station can be used to charge a second one of the energy storage devices. If the energy store is sufficiently charged by means of the second charging station, so that the energy store is fully charged or so that the current state of charge reaches or exceeds this level, and the motor vehicle is not driven directly from the second charging station, for example, by its driver, the motor vehicle is transported from the second charging station into the waiting area, for example, by means of a transport platform. Alternatively, it is conceivable, for example, if the energy store is completely or at least such charged by means of the first charging station or by means of the second charging station that the state of charge of the energy store exceeds or reaches this level, for the driver to drive away directly from the first charging station or from the second charging station, so that the motor vehicle is transported into the waiting area without or with the aid of the transport platform. However, if it is determined that the driver has not driven the vehicle away from the first or second charging station simultaneously or within a waiting period after the end of the charging process at the first or second charging station, the vehicle is transported from the first or second charging station into the waiting area by means of the transport platform. As a result, excessively long blocking of the charging station can be avoided, and the charging station can be provided particularly quickly for the further energy store.
A further embodiment is characterized in that the first charging station is configured as a rapid charging station having a first maximum charging power for charging the respective energy store. In this case, it has proven to be particularly advantageous if the second charging station has a second maximum charging power for charging the respective energy store, which is smaller than the first maximum charging power. Preferably, the second maximum charging power is at least 100 kw, in particular at least 200 kw, less than the first maximum charging power. Thus, for example, the second charging station is configured as a standard charging station. According to the invention, a combination of a fast charging infrastructure and a standard charging infrastructure is therefore provided, by means of which a charging process for charging the energy store is carried out. A particularly high economy of the device can thereby be achieved, so that the energy store can be charged by means of the device both in a time-and cost-effective manner. This combination of a fast charging infrastructure and a standard charging infrastructure allows a particularly efficient use of the fast charging infrastructure and thus a fast charging station. If, for example, the respective energy store is charged by means of a rapid charging station in such a way that the charge state of the respective energy store can no longer be charged at the first maximum charge power, but can at most be charged at a significantly lower charge power than this, this can be determined by the device and the motor vehicle with the energy store can be automatically transported by means of a transport system from the rapid charging station to a standard charging station, at which charging station the energy store can be completed. In this way, a cost-effective quick charging station can be used effectively and efficiently, and at the same time, a particularly advantageous charging of a particularly large number of energy stores over time can also be achieved.
In a further particularly advantageous embodiment of the invention, the device, in particular the electronic computing device, is designed to determine the respective actual state of charge of the respective energy store. In particular, the actual state of charge is understood to be the actual state of charge of the energy store before charging the energy store. Thus, for example, the device, in particular the electronic computing device, is designed to determine the respective actual state of charge of the respective energy store before charging the respective energy store. Furthermore, the actual state of charge may relate to the actual state of charge of the respective accumulator during charging of the respective accumulator, i.e. to the state of charge of the respective accumulator caused by the charging. The device, in particular the electronic computing device, is therefore preferably designed to determine the respective actual state of charge, in particular the current state of charge, of the respective energy store during the charging of the respective energy store. The actual state of charge may furthermore relate to, for example, the actual state of charge of the respective energy store after charging, so that, for example, the device, in particular the electronic computing device, is designed to determine the respective actual state of charge of the respective energy store after charging the respective energy store. The actual state of charge thus relates, for example, to the state of charge of the respective accumulator, in particular current and/or determined at a certain point in time by the device. Depending on the determined actual state of charge, the motor vehicle can be transported and thus moved particularly advantageously and in accordance with the requirements by means of the transport system. In particular, the charging station can thus be used effectively and efficiently in order to charge the energy store in a satisfactory manner. For example, the actual state of charge is determined, in particular detected, when the respective motor vehicle is driven over or into the respective charging station. For example, the respective actual state of charge can be measured and/or calculated, in particular by means of the respective charging station. It is furthermore conceivable to determine the actual state of charge as a function of the inputs carried out by the respective driver. For example, the device, in particular the charging station, has an input device by means of which a person, for example a respective driver of a respective motor vehicle, can perform an input, in particular into the device. For example, an input by a person or a driver is detected by means of the input device, wherein the actual state of charge is determined from the input. In general, for example, the driver may input the actual state of charge. It is furthermore conceivable that the respective motor vehicle provides an information signal which characterizes the current actual state of charge of the respective energy store. The device may receive the information signal and determine therefrom an actual state of charge.
Furthermore, it has proven to be particularly advantageous if the device, in particular the electronic computing device, is designed to determine a respective desired state of charge of the respective energy store. The desired state of charge is, for example, a state of charge that is different from the actual state of charge and that is greater than the actual state of charge, in particular, that should be reached or regulated starting from the actual state of charge by a corresponding charge, that is to say by a corresponding charging process. For example, when the driver does not implement a particular input, the respective maximum state of charge of the respective accumulator may be used as the desired state of charge. It is furthermore conceivable for the driver to predefine a desired charge state, in particular by input via an input device, and for this reason it is conceivable for at least one driver-induced input to be detected by means of an input device of the apparatus, on the basis of which the desired charge state is determined. The determination of the desired state of charge enables a particularly advantageous planning of the charging process, so that the energy store can be charged particularly advantageously over time.
A further embodiment is characterized in that the device, in particular the electronic computing device, is designed to determine a current actual charging power with which the respective energy store is currently charged by means of the respective charging station. The determined current actual charging power is, for example, information or measured values, by means of which the following logic can be implemented, for example: as soon as the current actual charging power, with which one of the energy stores is currently charged by means of the second charging station (standard charging station), falls below the second maximum charging power of the second charging station, the one of the energy stores can continue to be charged there, that is to say by means of the second charging station, so that it can remain on the second charging station and does not have to be transported to the first charging station (quick charging station), since the first maximum charging power of the quick charging station, which is higher than the second maximum charging power of the standard charging station, can no longer be used to charge the one of the energy stores faster than with the standard charging station. Thus, unnecessary transportation of the respective motor vehicle can be avoided.
In this case, it has proven to be particularly advantageous if the device is configured for automatically conveying the respective motor vehicle from the pick-up area to the respective charging station and/or from the first charging station to the second charging station and/or from the respective charging station to the waiting area as a function of the actual state of charge and/or as a function of the desired state of charge and/or as a function of the actual charging power by means of the conveying system. In this way, the respective motor vehicle can be positioned in a desired manner at the respective location, for example at the respective charging station and at the waiting area, so that the charging station can be used effectively and efficiently and excessive blocking of the charging station can be avoided. If the difference between the actual state of charge and the maximum state of charge or between the actual state of charge and the desired state of charge of the respective energy store is determined, for example, as a function of the actual state of charge and, if appropriate, as a function of the desired state of charge, is so small that the energy store can also be brought from the actual state of charge to the desired state of charge by means of the standard charging station, and therefore by means of the second charging station which is just idle, so that the energy store can be brought from the actual state of charge to the desired state of charge faster or as quickly than by waiting for the quick charging station to become idle and to charge the energy store by means of the quick charging station, the motor vehicle can be automatically transported from the extraction area to the standard charging station (second charging station), for example by means of the transport system. A corresponding situation can be implemented in order to realize a motor vehicle from a first charging station to a second charging station. For example, one of the energy stores can be initially placed in a high state of charge by means of a quick charging station, and then the charging of the one energy store can be completed by means of a standard charging station, while the other energy store is placed in a high state of charge by means of a quick charging station. In this way, a turret-type or warehouse-type charging of the energy storage device can be achieved, so that the device can be designed and operated particularly economically, and so that a particularly large number of energy storage devices can also be charged in a time-advantageous manner.
If, for example, it is determined that the respective energy store has the desired charge state and the motor vehicle then fails to travel away immediately or during a waiting time by the driver, the motor vehicle is automatically transported into the waiting area by means of the transport system. This can reliably avoid excessively long blocking of the charging station. In a further particularly advantageous embodiment of the invention, the device, in particular the electronic computing device, is designed to determine a charging time, which is required for bringing the actual state of charge to the desired state of charge by charging, at least as a function of the actual state of charge and as a function of the desired state of charge and preferably also as a function of the actual current charging power, so that the energy store is charged in such a way that, in particular starting from the actual state of charge, it has or reaches the desired state of charge. The charging time is information on the basis of which the vehicle can be allocated to the charging station in a particularly satisfactory manner, and the respective driver can schedule his time in a meaningful way outside the vehicle, in particular during charging. Furthermore, the digital route planner and/or the charging planner can select one of the charging stations, which is determined to be particularly advantageous in terms of the respective energy store, taking into account the current charging time from the charging station, in particular in terms of being able to advantageously charge the energy store by means of the device time.
For example, provision is made for the transport system to automatically transport the respective motor vehicle from the pickup area to the respective charging station and/or from the first charging station to the second charging station, automatically as a function of the determined charging time. In particular, it can be provided that a respective charging station is selected as a function of the determined charging time. Furthermore, it has proven to be particularly advantageous if the device, in particular the electronic computing device, is designed to determine a corresponding, in particular current, charging power with which, in particular, the corresponding energy store is currently charged by means of the corresponding charging station.
In this case, it has proven to be particularly advantageous if the device is configured for conveying the respective motor vehicle from the pick-up area to the respective charging station and/or from the first charging station to the second charging station by means of the conveying system as a function of the determined, in particular current, charging time. This allows particularly efficient use of the charging infrastructure, in particular the quick charging station. The invention can be realized, for example: when it is determined, for example, that the charging power does not or no longer corresponds to the first maximum charging power or is smaller than, for example, a predefined or predefinable limit value, or when, for example, the difference between the determined current charging power (with which the energy store is currently charged) and the first maximum charging power exceeds, in particular, a predefined or predefinable limit value, the respective motor vehicle is automatically moved by means of the conveyor system from the rapid charging station to a standard charging station which is more advantageous with respect to the cost of the rapid charging station. The quick charging station can thus be provided for an energy store that can be charged at or at least approximately at a first maximum charging power, so that the energy store as a whole can be charged particularly advantageously over time.
In a further particularly advantageous embodiment of the invention, the device, in particular the electronic computing device, is designed to transmit the determined charging time, in particular wirelessly, to at least one device external to the device. The external device may be, for example, a navigation system of the motor vehicle or one of the motor vehicles or a mobile terminal of the user, for example one of the drivers, so that the navigation system or the mobile terminal can be informed of the charging time. The navigation system can, for example, plan the route accordingly, in particular such that the motor vehicle arrives at the extraction area, for example, in such a way that the waiting time is as small as possible or even zero, after which the motor vehicle can be transported to one of the charging stations by means of the transport system. By transmitting the charging time to the mobile terminal, it is possible, for example, to inform a corresponding driver located outside the corresponding motor vehicle of, for example, the remaining charging time. In this connection, the driver can therefore plan his time correspondingly outside the motor vehicle.
A further embodiment is characterized in that the device is configured for transmitting, in particular wirelessly, data to at least one mobile terminal device external to the device, the data representing a current state of the respective motor vehicle during charging of an energy store of the respective motor vehicle. For example, the current state comprises the determined current actual state of charge, so that the respective driver can recognize or retrieve the respective current actual state of charge during charging by means of his mobile terminal device while he is located outside the motor vehicle. In this way, the driver can drive the motor vehicle away from the respective charging station immediately after the end of the charging process or during a waiting time. If this does not occur, i.e. the motor vehicle is not driven away from the charging station by the driver after the end of the charging process and within a waiting time, for example, the motor vehicle is automatically transported from the charging station into the waiting area by means of the transport system. The driver can then drive his motor vehicle away from the waiting area. In particular, it is conceivable that the state comprises the current position of the respective motor vehicle. Thus, for example, the driver can be informed of where the motor vehicle is currently located in the device or in which region. Thus, the driver does not have to expend on searching for his motor vehicle.
Finally, it has proven to be particularly advantageous if the device has at least one output device arranged on or in the extraction region, by means of which an optical, that is to say a signal which can be perceived by the human eye and is also referred to as an indicator signal, is able to be output, which signal characterizes a start time at which the energy store of the motor vehicle currently located in the extraction region begins to charge. Thus, for example, a driver still in the motor vehicle can be notified of the start time, so that the driver can estimate how long he has to wait for the charging process to start. In this way, the driver can plan his time particularly well outside the motor vehicle.
A second aspect of the invention relates to a method for charging an electrical energy store of a motor vehicle. Preferably, the respective energy store relates to a battery, in particular a high-voltage battery. Preferably, the respective energy store is a high-voltage component whose voltage, in particular the motor operating voltage or the nominal voltage, is preferably greater than 50 volts, in particular greater than 60 volts, and very preferably several hundred volts. The motor vehicle may be a hybrid or electric vehicle, in particular a Battery Electric Vehicle (BEV). In this method, the energy store is supplied with electrical energy by means of a plurality of charging stations, in particular of the device according to the first aspect of the invention, and is thereby charged, in particular such that electrical energy is stored in the energy store. In particular, in the method, it is provided that at least two of the energy accumulators are charged simultaneously by means of a charging station and therefore by means of the device, so that, for example, a first of the energy accumulators is charged by means of a first of the charging stations, while a second of the energy accumulators is charged by means of a second of the charging stations.
In order to be able to charge the energy store in a particularly advantageous manner over time, it is now provided according to the invention that the respective motor vehicle is automatically transported by means of the transport system of the device from the withdrawal area spaced apart from the charging stations to the respective charging station, from the first charging station to the second charging station and from the respective charging station into the waiting area spaced apart from the charging stations and from the withdrawal area. Advantages and advantageous designs of the first aspect of the invention may be regarded as advantages and advantageous designs of the second aspect of the invention and vice versa.
For charging the respective energy store of the respective motor vehicle by means of the respective charging station, the respective energy store or the respective motor vehicle is at least electrically connected to the respective charging station, in particular via at least one wire. Via the wire, the charging station can supply electrical energy for charging the respective energy accumulator, thus transmitting electrical energy to the respective energy accumulator. It is conceivable here for the respective energy store to be connected manually and here, for example, by the respective driver to the respective charging station or to the respective line and to the respective charging station via the line. Or by means of the device, for example, the respective charging station, in particular the respective conductor, and the respective charging station is automatically connected at least electrically to the respective energy store via the respective conductor. The energy store can thus be charged particularly advantageously over time.
Drawings
Further details of the invention are found in the following description of the preferred embodiments with the aid of the accompanying drawings. Fig. 1 is a schematic illustration of an apparatus according to the invention for charging an electrical energy store of a motor vehicle.
Detailed Description
Fig. 1 shows a schematic illustration of a device 1 for charging an electrical energy store of a motor vehicle 2. In the exemplary embodiment shown in fig. 1, the respective motor vehicle 2 (also referred to as a vehicle for short) is a motor vehicle, in particular a passenger car. The device 1 has charging stations 3 and 4, by means of which the respective energy store of the respective motor vehicle 2 can be supplied with electrical energy and can thus be charged.
In order to be able to charge the energy store of the motor vehicle 2 in a particularly advantageous manner over time, the device 10 has a conveying system 5 by means of which the respective motor vehicle 2 can be automatically conveyed from the extraction area a spaced apart from the charging stations 3 and 4 to the respective charging station 3, 4, from at least one first charging station of the charging stations 3, 4 to at least one second charging station of the charging stations 3, 4 and from the respective charging station 3, 4 into the waiting area W spaced apart from the charging stations 3, 4 and from the extraction area a. The device 1 and the method for charging an energy store are described below with the aid of two motor vehicles 2 denoted by K1 and K2 and with the aid of two charging stations 3, 4 denoted by L1 and L2. In the embodiment shown in fig. 1, charging station 3 and thus charging station L1 is configured as a quick charging station, while charging station 4 and thus L2 is configured as a standard charging station. This is to be understood as meaning that the respective quick charging station has a first maximum charging power for charging the respective energy store. The first maximum charging power is, for example, at least or exactly 350 kw. The respective standard charging station has a second maximum charging power for charging the respective energy store, which is smaller than the first maximum charging power, wherein the second maximum charging power is, for example, at least 100 kw, in particular at least 200 kw, smaller than the first maximum charging power.
In the embodiment shown in fig. 1, the transport system 5 is configured as a platform system or a tray system. The transport system 5 here comprises transport platforms 6, which are also referred to as platforms or transport platforms and are configured, for example, as pallets. The method and the apparatus 1 are explained below with the aid of two conveying platforms 6 denoted P1 and P2.
In order to charge, for example, an energy store of motor vehicle K1, motor vehicle K1 to be charged, that is to say motor vehicle K1 with an energy store to be charged, is parked by its driver in extraction area a and in particular on transport platform P1 located in extraction area a. The driver of motor vehicle K1 drives motor vehicle K1 forward or backward, for example, onto transport platform P1 in extraction area a. The current actual state of charge of the energy store of motor vehicle K1 is determined before motor vehicle K1 is parked on transport platform P1, during parking of motor vehicle K1 on transport platform P1 and/or after parking of motor vehicle K1 on transport platform P1, for example by means of device 1, in particular by means of the electronic computing device of device 1. For example, the actual state of charge is automatically determined, in particular detected, or the current actual state of charge is determined based on driver information. For example, vehicle K1 provides an information signal, in particular automatically, in particular wirelessly, wherein the information signal characterizes a current actual state of charge of an energy store of vehicle K1. The device 1, in particular the electronic computing device of the device 1, receives the information signal and determines from the information signal the current actual state of charge of the energy store of the motor vehicle K1 prior to charging. Alternatively or additionally, the device 1 may comprise input means, also referred to as a human-machine interface, which are not shown in detail in fig. 1. The driver of motor vehicle K1 inputs into device 1, for example, via an input device, wherein the driver's input is detected by means of the input device. The current actual state of charge is determined from an input indicative of the current actual state of charge prior to charging. It is furthermore conceivable for the driver to input his charge request, that is to say the desired charge state of the energy store of motor vehicle K1, into the input device and thus into device 1 via the input device.
The desired state of charge is a state of charge at which the energy store of motor vehicle K1 is or should be set starting from the actual state of charge by charging the energy store of motor vehicle K1 by means of device 1, that is to say by means of at least one of charging stations 3, 4 of device 1. The charging of the respective energy store of the respective motor vehicle 2 is also referred to as a charging process or is carried out during the charging process. From the determined actual state of charge prior to charging and from the determined desired state of charge, an energy requirement is determined, for example by means of the device 1, in particular by means of an electronic computing device, which is required in order to increase the actual state of charge to the desired state of charge by charging. The energy requirement is thus the energy that can be supplied to the energy store of the motor vehicle 2 by means of the device 1 in order to place the energy store of the motor vehicle K2 from the actual state of charge into the desired state of charge, thus equalizing the actual state of charge with the desired state of charge. Alternatively or additionally, a charging time is determined by means of the device 1, in particular by means of an electronic computing device of the device 1, which is required to place the energy store of the motor vehicle K1 from the actual state of charge into the desired state of charge by charging the energy store of the motor vehicle K1 to be carried out by means of the device 1. The aforementioned actual state of charge is also referred to as a first actual state of charge, which is determined by means of the device 1 prior to charging the energy store of the motor vehicle K1. The energy requirement and/or the charging time characterizes a so-called charging requirement, which is determined for the respective motor vehicle 2 by means of the device 1.
As can be seen from fig. 1, the device 1 also has an intermediate region ZB, also referred to as a transition region, in which the motor vehicle to be charged, i.e. the motor vehicle 2 with the energy store to be charged, is temporarily parked, so to speak temporarily stored. The middle area ZB is different from the charging stations 3, 4, the extraction area a, and the waiting area W.
Firstly, for example, motor vehicle K1 is transported, in particular automatically, from extraction area a to intermediate area ZB and into this intermediate area by means of transport platform P1, and can be said to be temporarily stored, that is to say temporarily parked, in intermediate area ZB, at least for a short time, in particular during the time when the driver of motor vehicle K1 is located outside motor vehicle K1. Based on the charging requirements of the motor vehicle 2 temporarily stored in the intermediate region ZB and waiting for it and, for example, on the basis of the actual power of the device 1, which is also referred to as the system or the overall system, in particular with respect to the charging of the energy store, in particular simultaneous charging, in particular the calculation of the temporal flow of the charging process to be carried out by means of the device 1 for charging the energy store of the motor vehicle 2 by means of an electronic computing device.
With the aid of the conveying platform 1, the motor vehicle K1 is first conveyed into the intermediate region ZB and temporarily stored there, in particular if no charging stations 3, 4 or only such charging stations 3, 4 are idle at the time when the motor vehicle K1 is parked on the conveying platform P1, for which charging stations it has been determined that they are not advantageous for charging the energy store of the motor vehicle K1, i.e. if it has been determined that the energy store of the motor vehicle K1 can be charged more quickly than if the motor vehicle K1 is conveyed directly from the extraction region a to the idle charging stations 3, 4 and is charged there, when the motor vehicle K1 is temporarily stored in the intermediate region ZB.
In fig. 1, the transport paths of the device 1, which are referred to as the driving or transport paths, are denoted by 7, wherein these transport paths are illustrated by arrows in fig. 1. The transport platform 6 can be moved at least translationally along the transport path 7, so that the motor vehicle 2 can be moved at least translationally along the transport path 7 by means of the transport platform 6 and thus transport the motor vehicle. As can also be seen from fig. 1, the respective transport platform 6 is moved rotationally and in this case can be rotated in particular about a respective axis of rotation extending in the vertical direction, as a result of which the respective motor vehicle 2 resting on the respective transport platform 6 can be rotated. It can be seen that the respective transport platform 6 can be moved at least translationally, in particular along the respective transport path 7, relative to the charging stations 3, 4, whereby the respective motor vehicle 2 can accordingly be moved at least translationally. Furthermore, in the exemplary embodiment shown in fig. 1, the respective transport platform 6 can be rotated about a respective rotation axis extending in the vertical direction relative to the respective charging station 3, 4, as a result of which the respective motor vehicle 2 can also be rotated. As a result, the motor vehicle 2 can be transported in a space-saving and satisfactory manner. In fig. 1, the surface for moving, in particular, the transport table 6 is denoted by F.
As can be seen from fig. 1, vehicle K2 is first charged by means of charging station L1, and a third of vehicles 2, denoted by K3, is charged, for example, by means of charging station L2. For example, it is determined by means of the device 1 that the motor vehicle K3 or its energy store reaches the desired state of charge in a short time, that is to say in the near future, and that the energy store of the motor vehicle K2 has such an actual state of charge, which is derived from the state of charge, in a short time that the charging power drops below a threshold value, with which the energy store of the motor vehicle K2 can be charged maximally or as quickly as possible by means of the charging station L1. If the energy store of motor vehicle K3 has reached its desired charge state, motor vehicle K3 is transported from charging station L2 into waiting area W by means of transport platform 6, on which motor vehicle K3 is parked, from which waiting area the driver of motor vehicle K3 can pick up motor vehicle K3 and drive off. When the charging station L1, in particular the current charging power, falls below the threshold value, the motor vehicle K2 is automatically transported from the charging station L1 to the charging station L2 by means of the transport platform P2. The energy store of motor vehicle K2 is then charged by means of charging station L2, in particular until the energy store of motor vehicle K2 has the desired state of charge. Since the charging station L1 is idle by automatically transporting the motor vehicle K2 from the charging station L1 to the charging station L2, the motor vehicle K1 is automatically transported from the intermediate area ZB to the charging station L1 by means of the transport platform P1. The energy store of the motor vehicle K1 is supplied with electrical energy by means of the charging station L1 and is thereby charged. Since the actual state of charge of the energy store of motor vehicle K1, for example, which is determined before the energy store of motor vehicle K1 is charged, is very small, the energy store of motor vehicle K1 can be charged by charging station L1 with a charging power which corresponds to the first maximum charging power or which deviates only slightly from the first maximum charging power, and is therefore not less than the threshold value.
If, for example, the energy store of motor vehicle K2 is charged by means of charging station L2, so that the energy store of motor vehicle K2 has the desired charge state, and motor vehicle K2 is not picked up by the driver of the motor vehicle after the end of the charging and within a predefined or predefinable waiting time and is driven directly away from charging station L2, motor vehicle K2 is transported from charging station L2 by means of transport platform P2 into waiting area W. The driver of motor vehicle K2 can then pick up motor vehicle K2 from the waiting area and drive away, that is to say from below conveying platform P2.
It can be seen that after the respective driver has parked the respective motor vehicle 2 in the extraction area a on the transport platform 6, it can be removed from the motor vehicle 2 and can remain outside the respective motor vehicle 2 during the respective charging. After the end of the respective charging or charging process, the driver can return his motor vehicle 2 and take his motor vehicle 2 away from the respective charging station 3, 4 or from the waiting area W and drive away.
An output device 8 of the apparatus 1 is arranged next to the extraction area a, wherein the output device 8 has an electrical or electronic display 9. On the display 9, an optical signal is displayed and thus output, which characterizes or displays the start time at which the charging of the energy store of the motor vehicle 2 currently located in the extraction area a on the conveyor table 6 arranged there begins. In particular, the start time is displayed when entering the device 1 or when entering the conveyor table 6 arranged in the extraction area 6. The signal is thus information by means of which the driver of the motor vehicle 2 located in the extraction area a is informed of when the motor vehicle 2 is to be transported to one of the charging stations 3, 4 and begins charging there.
For example, a current second actual state of charge of the energy store of motor vehicle K1 is determined by means of device 1 during the charging of the energy store of motor vehicle K1. In this case, the device 1 provides data, in particular wirelessly, which characterize the current state of the motor vehicle K1 during the charging of the energy store of the motor vehicle K1. For example, the data are transmitted, in particular wirelessly, to the mobile terminal of the driver of the motor vehicle K1, in particular during a stay of the driver of the motor vehicle K1 outside the motor vehicle K1. An electronic computing device of the driver of the motor vehicle K1, for example, in the form of a mobile terminal embodied as a mobile phone or a smart phone, executes an application, also referred to as App or software App, by means of which the data provided by the device 1 are received. The current state of motor vehicle K1 is displayed on a display of the mobile terminal, in particular electronic or electrical, in particular during charging. The current state comprises, for example, a current second actual state of charge of the energy store of motor vehicle K1. Thus, for example, a current second actual state of the energy store of motor vehicle K1 is displayed on a display of the mobile terminal. Alternatively or additionally, the start time and/or the end time of the charging process for charging the energy store of motor vehicle K1 is displayed on the display of the mobile terminal. The start time is the time at which charging of the energy store of motor vehicle K1 begins, and the end time is the time, in particular the expected time, at which the charging process for charging the energy store of motor vehicle K1 ends, in particular the expected end.
It is furthermore conceivable that information about the current waiting time (for example, the driver has to wait for the waiting time until the charging process for charging the energy store begins) is provided via a server, which is also referred to as a backend and is external to the device 1, for example, in particular a route planner, a navigation system and/or a software application, which is executed, for example, on a mobile terminal. In this way, the charging process can be rationally planned.
As soon as the quick-charging position, for example the charging station L1, is idle, the motor vehicle K1 to be charged is transported to the charging station L1 without the action of a driver or operator, in particular by means of the transport platform P1 on which the motor vehicle K1 is parked. After the motor vehicle K1 reaches the charging station L1, the motor vehicle K1 or its energy store is connected to the charging station L1 via the line 10 automatically or manually. For this purpose, for example, the conductor 10 and the corresponding contact element of the motor vehicle K1 are inserted into one another.
The sequence according to which the motor vehicle 2 is charged can be carried out in the sequence in which the motor vehicle 2 is driven into the device 1 and/or is parked on the transport platform 6 or in accordance with another strategy. It is conceivable that a particular vehicle, for example a rescue vehicle or an emergency mission vehicle, is prioritized over other vehicles or vehicle types and/or that a reduced waiting time or a reduced waiting time can be provided by means of a corresponding price system.
For example, depending on the operating strategy or on the full load condition of the device 1, the motor vehicle K1 is held on or in the charging station L1, for example, until, for example, the energy store of the motor vehicle K1 has reached its desired charge state or the charging power for charging the energy store of the motor vehicle K1 by means of the charging station L1 has fallen below a defined or predefinable minimum value or level. If this is the case, motor vehicle K1 is automatically transported from charging station L1 to an idle charging station in charging stations 4, for example to charging station L2, by means of transport platform P1, in particular after motor vehicle K2 has been transported away therefrom by means of transport platform P2 and, for example, into waiting area W. The energy store of vehicle K1 is then charged by charging station 4, in particular charging station L2, that is to say until the energy store of vehicle K1 has the desired charge state.
After the energy store of motor vehicle K1 has reached its desired state of charge, also referred to as target state of charge, motor vehicle K1 is driven away from charging station L1 or from one of charging stations 4, in particular from charging station L2, or if this does not occur within a waiting time, motor vehicle K1 is transported into waiting area W by means of transport platform P1 and is parked there.
The device 1 is designed such that the vehicle can be driven manually on each parking space, that is to say at each location, and thus for example from each charging station 3, 4, from the intermediate zone ZB and from the waiting zone W, that is to say from the respective transport platform 6. The device 1 is thus fault-tolerant and provides flexibility for short-term planning changes by the user or device operator.
Furthermore, the following is conceivable: for example, the actual current charging power is determined by means of the device 10, with which the energy store motor vehicle K3 is charged, for example, by means of the charging station L2. If it is determined, for example, that the current actual charging power (with which the energy store of motor vehicle K3 is currently charged by means of charging station L2 (standard charging station)) falls below the second maximum charging power of charging station L2, i.e. is smaller than the second maximum charging power, the energy store of motor vehicle K3 can be charged further by means of charging station L2, in particular until the energy store of motor vehicle K3 has reached its desired state of charge. Thus, the motor vehicle K3 is prevented from being transported to one of the charging stations 3 (quick charging stations) in order to charge the energy store of the motor vehicle 3 by means of the one charging station 3, since this offers no technical advantage since the first maximum charging power of the one charging station 3, which is higher than the second maximum charging power of the charging station L2, can no longer be used to charge the energy store of the motor vehicle K3 more quickly than by means of the charging station L2. In other words, the energy store of vehicle K3 cannot be charged more quickly by means of one of the quick charging stations than by means of charging station L2, so that vehicle K3 can rest on charging station L2 and complete the charging there.
